Ok, so if I am spot washing flux off a circuit board or cleaning the face of an epoxy insulator to remove silicone dielectric grease what am I supposed to use?

Brian,  I know you are very environmentally concerned.  IPA and the like have been used for years by our industry and it is usually the default cleaner for everything.  And yes I know alcohols do a better job of spreading contaminates than removing them.  What then, if spot cleaning, should be used?  (I know, "it depends".)  Manufacturing is always complaining that Engineering creates designs and processes that take too much time, but they work if done as designed.  Finding a practical solution and changing the mindset is no small task.

I look forward to your sage wisdom.

Phil

Yes! absolutely! And it is highly toxic, to boot, with ingress to the 
body by all means, including cutaneous. IMHO, avoid it!
